Summary of Changes

Hello @schultek, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request represents a significant architectural shift, migrating the site's learning resource filtering and underlying web framework from Eleventy to Jaspr. This change involves a complete overhaul of the build and deployment processes, eliminating Node.js and npm dependencies in favor of a pure Dart-based solution. The project structure has been refactored to centralize Jaspr-related code, and numerous new components and extensions have been added to support the new framework's capabilities and maintain existing site features.

Highlights

• Technology Stack Migration: The learning resource filtering functionality has been migrated from an Eleventy-based system to Jaspr, a Dart-based web framework.
• Dependency Removal: Node.js and npm dependencies have been entirely removed from the project, streamlining the development environment.
• Build and Deployment Updates: Various build and deployment configurations, including Dependabot, Nix development environment, and Cloud Build pipelines, have been updated to reflect the new Jaspr-based architecture and Dart tooling.
• Site Structure Reorganization: The site's directory structure has been reorganized, with core site files now residing under a new 'site/' directory.
• New Components and Extensions: A comprehensive suite of new Jaspr components (e.g., buttons, cards, chips, dropdowns, feedback, OS selectors, TOC) and page extensions (e.g., attribute processing, code block highlighting, header extraction) have been introduced to support the new framework.

Code Review

This pull request successfully migrates the learning resource filtering functionality from JavaScript to Jaspr client components. The new implementation is well-structured, separating the search/filter controls (LearningResourceFilters) from the filter sidebar (LearningResourceFiltersSidebar) and using a ChangeNotifier for state management between them.

My review includes a couple of suggestions to improve the implementation: one to optimize state updates to avoid unnecessary rebuilds, and another to adopt a more declarative approach for managing the filter checkboxes, which will improve maintainability by removing direct DOM manipulation.
